摘要：
Two new species of the family Angarosphecidae, Angarosphex saxosus sp. nov. and Vitimosphex vividus sp. nov., from the Lower Cretaceous Yixian Formation of northeastern China are described and illustrated. Generic diagnoses are revised. The genera Palaeapis Hong, 1984, Mataeosphex: Zhang, 1985, and Calobaissodes Zhang, 1992 are synonymized under Angarosphex Rasnitsyn, 1975, and new combinations Angarosphex beiboziensis (Hong, 1984), comb. nov., Angarosphex venulosus (Zhang, 1985), comb. nov., and Angarosphex strigosus Zhang, 1992, comb. nov. are proposed. The genus Vitimosphex Rasnitsyn, 1975 is found reaching northeastern China in its distribution. New morphological data are presented to complete characteristics of the genera concerned.
